Recent developments in carbon nanomaterials-based electrochemical sensors for methyl parathion detection

Methyl parathion (MP), an organophosphorus insecticide, is commonly used in agricultural products for food preservation and pest control. Due to the severe threat it poses to food safety and the environment, monitoring MP residues has attracted much attention. Traditional spectroscopic and chromatographic methods have been used successfully to analyze MP in a wide range of samples; however, these approaches have several drawbacks, such as requiring specialized equipment, trained technicians, and extensive sample preparation time. Due to these restrictions, there is a growing demand for analysis methods that can reliably and quickly detect MP at trace quantities while also being quick, sensitive, and selective. Electrochemical sensors have emerged over the past few decades as a viable alternative to more time-consuming and laborious analysis methods for detecting MP. However, the performance of electrochemical sensors has been dramatically improved thanks to recent breakthroughs in nanoscience. This study offers an overview of the creation and operation of carbon nanomaterial-based electrochemical sensors (including carbon nanotubes (CNTs), graphene (Gr), and other carbon nanomaterials) to identify MP residues in waters, fruits, and vegetables. A brief discussion of the potential benefits, drawbacks, and future research prospects of MP electrochemical sensors based on carbon nanomaterials is also offered.
